java - JAVAFX 应用程序 UI 变得无响应

问题描述

我有一个基于 javafx 的桌面应用程序。唯一的要求是它必须连续运行 5-6 天。我处于测试阶段。

在此使用的 UI 组件：

在 6 个仪表中，3 个仪表和折线图必须在 1 秒内更新。为此，我使用了每秒更新此组件的线程。

我已经测试了这个应用程序近 3 次：

  1. 三天

  2. 26 小时（其中图表工作正常，仪表中的值正在更新，但仪表指针卡在特定值）

  3. 现在 24 小时，仪表指针在移动，但仪表值被卡住，折线图抽屉没有打开，只有汉堡包图标在变化。

日志中没有异常，UI 没有挂起，只是 Ui 组件没有响应。

我做了分析，但一切似乎都很好。我也读过这篇文章，但在他的情况下，ui 挂起，我对此没有任何问题，所有按钮都是可点击的，我可以毫无问题地更改屏幕。

重新加载后，屏幕全部恢复正常。

我用来更新组件的示例代码。

图书馆

  1. jfoenix-8.0.1-for-java8.jar Github
  2. fontawesomefx-8.9.jar bitbucket
  3. Medusa-8.0.jar jar- 下载

出于测试目的，我只更新一个仪表。系统配置是：

  1. 操作系统：Ubuntu 18.04 lts
  2. 处理器：英特尔酷睿 i5-8400
  3. 内存：8Gb

对此有任何想法。
